Creating SnapMirror relationships
You can use mirroring technology to replicate data from a source volume to a destination volume at regular intervals or on demand.
Before you begin 
•
The SnapMirror license must be enabled on both the source and the destination storage systems.
•
For SnapMirror volume replication, the capacity of the destination volume must be greater than or equal to the capacity of the source volume.
•
The SnapMirror destination volume must not be the root volume of a storage system.
•
Both source and destination systems must be managed by System Manager.
Note: During disaster recovery, when the source system is down, the Quiesce and Break operations can be performed by System Manager from the destination system.
•
You must have created the cluster peer relationship between the source cluster and the destination cluster.
About this task 
The storage system can either be the source system or the destination system for the new SnapMirror relationship that you create. You can create a volume SnapMirror relationship by using a FlexClone volume or its parent as the source volume. However, you cannot create a volume SnapMirror relationship by using either a FlexClone volume or its parent as the destination volume.
Steps 
1.
From the home page, double-click the appropriate storage system.
2.
Expand the Storage Virtual Machines hierarchy in the left navigation pane.
3.
In the navigation pane, select the SVM and click SnapMirror.
4.
Click Create.
5.
Type or select information as requested by the wizard.
6.
Confirm the details and click Finish to complete the wizard.
7.
Verify that the SnapMirror relationship you created is included in the list of SnapMirror relationships in the SnapMirror window.
If you choose not to initialize the SnapMirror relationship during creation, then it is not displayed in the SnapMirror window of the source system. You have to initialize it from the SnapMirror window of the destination system.
Note: System Manager does not record the storage system's fully qualified domain name (FQDN) in the snapmirror.conf file.
